1) The document discusses different types of teaching theories including formal, descriptive, and normative theories. Formal theories are syntactic in nature while descriptive theories are based on observations of learner characteristics. Normative theories establish teaching standards based on human teachers and students.
2) Descriptive theories include theories of instruction like Gagne's hierarchical theory and Bruner's cognitive development theory. Prescriptive theories analyze teaching variables like teacher activities, educational objectives, and components of learning.
3) Normative theories include cognitive theory of teaching, theory of teacher behavior, and general theories of teaching. The cognitive theory addresses teacher roles and objectives. Theory of teacher behavior defines teacher acts that induce learning. General theories assume teaching produces student behavior
